BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a punch press, and more particularly, to a punch press having a separating die for separating a small product from a sheet material.

[0002]

2. Description of the Related Art Conventionally, when a multi-cavity small product is processed by a turret punch, the micro joint portion is processed so that the product is not cut off during the processing. In general, the microjoint is separated by a dedicated die, and the small product is generally carried out by a discharge roller provided on the rear side table.

[0003] Further, a die for punching a punch press, which has been already known in Japanese Utility Model Application Laid-Open No. Sho 62-163090, is disclosed in Japanese Unexamined Patent Publication No. 62-163090.
Of the three rectangular separation dies having different clearances, the separation is performed using only a part of the appropriate clearance.

[0004]

By the way, in the above-mentioned conventional die for punch press punching, in the former case, a die dedicated for separation is provided, but only one die is provided. Since the work cannot be mounted on the holder, the clearance changes when the thickness of the work changes, so the mold must be replaced with a mold corresponding to the thickness. 5 to 20 minutes for this replacement
There was a problem that it took about a minute and it took time and effort.

In the method known from Japanese Utility Model Application Laid-Open No. 63-163090, the program is troublesome, and the punching length of one stroke is reduced, so that the connecting portion of the outline of the small product and the original work is reduced. If the length is too short, there is a problem that the work is shaky and a seam is formed in the outline of the small product.

[0006]

SUMMARY OF THE INVENTION In view of the above-mentioned conventional problems, the present invention comprises a plurality of punches and dies for punching a plate material, and the plate material is moved with respect to a position where the punch and the die are processed. In a punch press configured to be movable and positionable in X and Y axes directions and having a separating punch and a separating die for separating a small product from a plate material at a position adjacent to the processing position, A die holder is provided at a position below the punch for horizontal movement, and a plurality of separation dies having dimensions different by the clearance from the punch for separation are mounted on the die holder. It is configured such that it can be positioned at a position corresponding to the separating punch.
